How much current Raspberry Pi draw

Shown in the video is a low cost USB Voltage Current Multimeter, it show the voltage and current at USB port alternatively. Maybe it's not a professional equipment, I can use it to monitor monitor and estimate power consumption on my RPi.

In order to eliminate the extra power draw by accessories, the Raspberry Pi connect USB power cable and network cable only, for sure with SD Card also.
